Sorky, IME even if you are 100% on your dates, and then the MW comes up with something different because of LMP, none of it matters because they always always always go off the scan dates, (and they can change again at 20 weeks), unless your dates are wayyyyy out compared to the scan dates, then you may as well go off the scan dates in your mind, otherwise if you go the 2 weeks over by your dates, but still have another 2/3 days by their dates, you will be all worried for nothing.
TBH as well, even if you know exactly when you OV'ed, down to the second, it doesn't really matter because there is no telling how long it actually took for the sperm to penetrate the egg, and then for that to implant properly etc. so your dates and their dates are normally up to a few days apart IYKWIM?
Don't worry about symptoms, the day I got my first BFP, I felt sooooo pregnant, by the next day it was all gone, and has just slowly built back up again. People who have really bad sickness can (and sadly) do still MC, so symptoms are not a sign of a healthy pregnancy.
I don't know all of the stats on MC's, sure Google would find something though.
Ses, yep I have two boys, but quite a lot of family history issues with girls so I don't even think it is entirely possible for me to carry a healthy girl.
Cosmo, good plan about making the next thread title more open to those waiting
Hope BB is OK, I know she want's a break, but am worried about her.
